Even within Twisted (single-threaded) code, I would suspect a race
condition here, but I see that you are running the blocking stuff in
another thread, which opens all sorts of racy possibilities.

My advice is to add some extra log.msg invocations around buildbot to
see if you can figure out when the status is being updated, and why.
